Ansible looping through different item within the same task

Question

I want to apply the specific tag or tags for the ec2 instance to the attached EBS volumes. Form the amazon.aws.ec2_instance_info: I get the all information for the ec2 and then with

"{{ item | flatten |
    map(attribute='block_device_mappings') | flatten |
    map(attribute='ebs') | flatten |
    map(attribute='volume_id') }}"

we can extract the volume IDs, but it returns the list of IDs like below

[
  vol-xxxxxxx,
  vol-zzzzzzz,
]

How to make sure for each loop it chooses one of the volume IDs and passes it to amazon.aws.ec2_tag:

playbook:

---
- name: Ansible Test Playbook
  gather_facts: false
  hosts: localhost
  vars_files:
    - vars/regions.yaml

  tasks:
    - name: Gather information about all instances
      amazon.aws.ec2_instance_info:
        region: "{{ item }}"
      register: instance_info
      loop: "{{ region }}"

    - name: Copy tags from EC2 to EBS
      amazon.aws.ec2_tag:
        region: us-east-1
        resource: "{{ item | flatten |
                      map(attribute='block_device_mappings') | flatten |
                      map(attribute='ebs') | flatten |
                      map(attribute='volume_id') }}"
        state: present
        tags:
          "team": "{{ item | flatten |
                      map(attribute='tags') | flatten |
                      map(attribute='team') | join }}"
      loop: "{{ instance_info.results | map(attribute='instances') }}"

In addition to this, I want to iterate the list of regions

region: 
 - us-east-1 
 - us-east-2

Q: "Each loop passes one of the volume ids to amazon.aws.ec2_tag"

A: Declare volume_ids and teams (the same way you do it in the loop) and use them in the task

    - amazon.aws.ec2_tag:
        region: "{{ item.1 }}"
        resource: "{{ item.0 }}"
        state: present
        tags:
          team: "{{ teams }}"
      loop: "{{ volume_ids|product(region) }}"
      vars:
        volume_ids: "{{ instance_info.results|
                        map(attribute='instances')|flatten|
                        map(attribute='block_device_mappings')|flatten|
                        map(attribute='ebs')|flatten|
                        map(attribute='volume_id') }}"
        teams: "{{ instance_info.results|
                   map(attribute='instances')|flatten|
                   map(attribute='tags')|flatten|
                   map(attribute='team')|join }}"

Example of a complete playbook for testing

shell> cat pb.yml
- hosts: all

  vars:

    region: 
      - us-east-1
      - us-east-2

    instance_info:
      results:
        - instances:
            - tags:
                team: tag_X
              block_device_mappings:
                - ebs:
                    - volume_id: vol-xxxxxxx
            - tags:
                team: tag_Z
              block_device_mappings:
                - ebs:
                    - volume_id: vol-zzzzzzz

  tasks:

    - debug:
        msg: |
          amazon.aws.ec2_tag:
            region: "{{ item.1 }}"
            resource: "{{ item.0 }}"
            state: present
            tags:
              team: "{{ teams }}"
      loop: "{{ volume_ids|product(region) }}"
      vars:
        volume_ids: "{{ instance_info.results|
                        map(attribute='instances')|flatten|
                        map(attribute='block_device_mappings')|flatten|
                        map(attribute='ebs')|flatten|
                        map(attribute='volume_id') }}"
        teams: "{{ instance_info.results|
                   map(attribute='instances')|flatten|
                   map(attribute='tags')|flatten|
                   map(attribute='team')|join }}"

gives

shell> ansible-playbook pb.yml -l test_01
